Video recorded Sunday, July 31st, 2016 at 1:29 P.M. local San Francisco time.
A bird enters the netted courtyard through one of the many, many holes in the netting. The particular hole appears to be the smallest possible unintentional opening / defect. A single strand of material is broken forming a hole 1 square tall by 2 squares wide. The netting appears to be 2 inch mesh. The hole appears to be 2 by 4 inches. The bird dives through it with no trouble at all.
Other birds are also evident within the netted courtyard during the video.
The ongoing attempts to repair this netting continue and the birds are still able to enter through many flaws. Currently a trapdoor has been installed which is intended to only allow birds to exit despite that young are currently within the nests in the courtyard and parents need to be able to return to tend their young.
At this time no birds appear to be able to exit through the trap door nor through the gap beside the trapdoor which some birds had used previously to both exit and enter the courtyard. For the past few days the birds have been exiting by risking their lives crawling under masses of loose netting on the west roof.
The birds have many ways to enter and few, mostly dangerous means of exiting.
These birds need help.
